ADVANCES IN THE ASSESSMENT OF THE NEGATIVE SYMPTOMS OF THE PSYCHOTIC SYNDROME
TLDR
The psychotic syndrome encompasses a wide variety of psychopathological domains among which are the positive, negative, cognitive, disorganised and affective dimensions (van Os & Kapur, 2009).
The Evolving Nosology of Schizophrenia: Relevance for Treatment
TLDR
The revisions in the DSM-5 criteria for schizophrenia spectrum and other psychotic disorders are summarized and their implications for clinical practice discussed.

Deconstructing Schizophrenia
TLDR
This study and other studies detailing the various psychopathologies associated with the schizophrenia diagnostic class defined symptom dimensions that are the primary targets for clinical intervention as well as critical to diagnosis.
Early onset first episode psychosis: dimensional structure of symptoms, clinical subtypes and related neurodevelopmental markers
TLDR
The four factors model presented highlights “negative symptoms” as the most consistent factor; among positive symptoms, unusual thought content and conceptual disorganization resulted more distinctive of psychosis, at this age range, than perceptual abnormalities.

Predicting Long-Term Outcomes in First-Admission Psychosis: Does the Hierarchical Taxonomy of Psychopathology Aid DSM in Prognostication?
TLDR
Findings support a shift away from the exclusive use of categorical diagnoses and toward the incorporation of HiTOP dimensions for better prognostication and linkage with neurobiology.
[Changes to Schizophrenia Spectrum and other psychotic disorders in DSM-5].
This article provides an overview of the main changes in the chapter "Schizophrenia Spectrum and Other Psychotic Disorders" from DSM-IV-TR to DSM-5, which, once again, does not make allowance for…
Validity and utility of Hierarchical Taxonomy of Psychopathology (HiTOP): I. Psychosis superspectrum
TLDR
Evidence is synthesized on the validity and utility of the thought disorder and detachment spectra of HiTOP, which demonstrated substantially improved utility: greater reliability, larger explanatory and predictive power, and higher acceptability to clinicians.
The Concept of Schizophrenia: From Unity to Diversity
After over 100 years of research without clarifying the aetiology of schizophrenia, a look at the current state of knowledge in epidemiology, genetics, precursors, psychopathology, and outcome seems…

The genetic deconstruction of psychosis.
TLDR
Understanding of the brain mechanisms that link specific gene actions and products to the subjective experience of psychopathological symptoms is likely to be bridged by employing intermediate (or endo-) phenotypes in the domains such as cognition, neurophysiology, or neuroanatomy rather than relying upon clinical measures alone.
Schizophrenia, “just the facts” 4. Clinical features and conceptualization
Schizoaffective disorder: diagnostic issues and future recommendations.
TLDR
Schizoaffective disorder is a prototypic boundary condition that epitomizes the pitfalls of the current categorical classification system and should be omitted in future revisions of DSM, allowing the development of meaningful nomenclature that rests upon further rigorous investigation of differences and similarities between disorders.
How many and which are the psychopathological dimensions in schizophrenia? Issues influencing their ascertainment
Empirical validation of primary negative symptoms: independence from effects of medication and psychosis.
TLDR
Two factors, termed affective flattening and diminished motivation, exhibited similar loadings when the patients were both on and off medication, and this finding will aid in the identification of primary negative symptoms.
Exploring the borders of the schizoaffective spectrum: a categorical and dimensional approach.
Neuropsychological symptom dimensions in bipolar disorder and schizophrenia.
TLDR
Together, these data suggest that while the same underlying factor structure describes NP functioning in both groups, the profile of impairments appears to vary with the diagnosis.
Neuropsychological function and dysfunction in schizophrenia and psychotic affective disorders.
TLDR
Differences in NP performance between schizophrenia and psychotic affective disorders are largely quantitative, and a significant minority of schizophrenia patients are NP normal.

The NIMH-MATRICS consensus statement on negative symptoms.
TLDR
A consensus development conference was held to review the data relating to the existence of separate domains within negative symptoms, as a prerequisite for choosing appropriate measures of these domains in clinical trials and to examine issues that may interfere with treatment development.
